PHP - convert 9 to 09 (the month of September)

Question

Seems like this should be simple but I can't get it to work.

I have credit card expiration months in format n (without leading zeros) and need it to be m (with leading zeros)

How do I convert an n month to an m?

If your months run from 1 to 12 then simply check if the month is less than 10, if it is then put a 0 on the front by converting it to a string. — Chris Cousins, Aug 25 '18 at 02:24

@Sachi.Dila Thanks so much. Works like a charm. $new_mo = str_pad($expire_mo, 2, '0', STR_PAD_LEFT); — James, Aug 25 '18 at 02:45

You can use sprintf to automatically pad a value to 2 (or more) characters with leading zeros:

echo sprintf("%02d", 9);

function checkTime(i) {
    if (i < 10) {i = "0" + i};  // add zero in front of numbers < 10 because I'm fancy
    return i;
}

you can use sprintf function for this...

<?php
 $monthnumber = date('m');
